FIELD: chemistry.
SUBSTANCE: invention relates to method for obtaining renewable polyisobutene polymer, polyisobutene polymer, obtained thereof, method for obtaining renewable isobutene of high degree of purity and method for obtaining one or more oligomer isoalkenes. Method for obtaining renewable polyisobutene polymer contains the following stages: a) provision of olefin mixture, containing isobutene and one or more linear butenes, where said olefin mixture is obtained from renewable hydrocarbon source; b) contact of said olefin mixture with adsorbing microporous material, which has effective pore opening from 5E to 5.4 E, for from about 6 to about 24 hours in closed reservoir, with linear butenes being selectively adsorbed into microporous material; c) isolation of isobutene from contact with microporous material; and d) polymerisation of said renewable isobutene with obtaining said renewable polymer.
EFFECT: obtaining isobutene polymers from renewable sources.
